Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689658, here are decompositions:

31 + 8689627 = 8689658
67 + 8689591 = 8689658
337 + 8689321 = 8689658
349 + 8689309 = 8689658
379 + 8689279 = 8689658
409 + 8689249 = 8689658
547 + 8689111 = 8689658
619 + 8689039 = 8689658

Showing the first eight; more decompositions exist.
